DM1 adjustable vented coupler

DM1 infinitely adjustable vented coupler.  Includes 8x 6-32 screws.

The Korbanth/Parks DM1 kits came from the factory with two different sizes of threading and we have included two sets of threads to match. The majority of the sabers will accept both size's but one size will be pretty loose fitting and you do not want to use it that way. Use the set that fits your saber the best.
